She believes that this could have had an impact on how Canberra's railway was funded.

Records show that Griffin's proposed railway line — a permanent line that would travel through the city and connect to Sydney and Melbourne via Yass — was costed multiple times, by the engineer-in-chief and even by Griffin himself.

Bureaucrats then suggested alternative rail lines, some of which didn't go as far as Civic or travelled through the south, deviating from Griffin's plans.

"They had about five or six different options, and of course the one that was most favourable to the bureaucrats was the cheapest," Amy said.
